Abstract

Eastern spotted skunks Spilogale putorius are an understudied species that has experienced range-wide declines. Over the past 16 years, camera traps have become an increasingly common tool to monitor and understand their current distribution. To inform best surveying practices, we reviewed 16 camera trap studies specifically targeting this species. We focused on reported latency to initial detection and three main aspects of study design: seasonality of detections, baits and lures, and camera trap brands. Latency to initial detection ranged from 1–82 days with a mean of 17.1 days (SD = 9.1). Attractants varied among projects, but most (75%) used sardines as bait. The percentage of skunk detections tended to vary across the year, with the highest percentage of skunk detections occurring in March (92%). We conclude by suggesting best practices and directions for future research techniques that will aid in developing more efficient methods to address key knowledge gaps for this elusive species. Given the long timeframes for latency to initial detection monitoring individual sites for at least four weeks, with the use of bait, is likely the best strategy to detect Eastern spotted skunks. We encourage further experimental approaches on the effectiveness of different baits and lures, and how to increase latency to initial detection. Collectively, we hope this leads to the development of a standardized monitoring approach that could be implemented across studies and states within the Eastern spotted skunk’s range.

东方斑点臭鼬相机捕捉方法综述
东方斑点臭鼬是一种研究不足的物种,经历了大范围的衰退。在过去的16年里,相机陷阱已经成为监测和了解其当前分布的一种越来越常见的工具。为了了解最佳调查实践,我们回顾了16项专门针对该物种的相机陷阱研究。我们重点关注了报告的初始检测延迟和研究设计的三个主要方面:检测的季节性、诱饵和诱饵以及相机陷阱品牌。首次检测的潜伏期为1-82天,平均17.1天(SD=9.1)。不同项目的引诱剂各不相同,但大多数(75%)使用沙丁鱼作为诱饵。全年发现臭鼬的百分比往往各不相同,其中3月份的臭鼬发现百分比最高(92%)。最后,我们提出了未来研究技术的最佳实践和方向,这将有助于开发更有效的方法来解决这个难以捉摸的物种的关键知识差距。考虑到最初检测的延迟时间很长,使用诱饵监测单个地点至少四周可能是检测东方斑点臭鼬的最佳策略。我们鼓励进一步研究不同诱饵和诱饵的有效性,以及如何增加初始检测的延迟。总的来说,我们希望这能导致一种标准化的监测方法的发展,该方法可以在东部斑点臭鼬范围内的研究和州内实施。

期刊介绍: Journal of Fish and Wildlife Management encourages submission of original, high quality, English-language scientific papers on the practical application and integration of science to conservation and management of native North American fish, wildlife, plants and their habitats in the following categories: Articles, Notes, Surveys and Issues and Perspectives. Papers that do not relate directly to native North American fish, wildlife plants or their habitats may be considered if they highlight species that are closely related to, or conservation issues that are germane to, those in North America.
